not clear how to switch from classic to regular eth chain #3113

Closed jpritikin closed 7 years ago

jpritikin commented 7 years ago

System information

Version: 1.5.0-unstable (1.4.16-4fced097) Protocol Versions: [63 62] Network Id: 1 Go Version: go1.5.1 OS: linux GOPATH= GOROOT=/usr/lib/go

Expected behaviour

I sync'd the eth classic chain. I expected to be able to trash the chain and re-sync the regular eth chain.

Actual behaviour

The -support-dao-fork option is no longer supported. I tried to sync the regular eth chain and got eth classic instead. How do I switch back?

Steps to reproduce the behaviour

geth --support-dao-fork

fjl commented 7 years ago

Resyncing with develop branch should land you on the non-classic chain.

I tried to sync the regular eth chain and got eth classic instead.

Which commands did you use?

geth --fast

Maybe an old config.rlp was sitting in ~/.ethereum?

There's no way to switch from ETC to ETH apart from doing a sync from scratch. Please delete your chaindata folder and start a new run of geth --fast. Please make sure you're using a release from the upstream Ethereum account and not some ETC version that has the DAO fork removed.

Can you make 'geth removedb' also remove the config.rlp file? I think that's the only part that confused me.

Thanks.

We don't use config.rlp. This file is created by cpp-ethereum.

Don't you store whether to support or oppose the DAO fork somewhere?

fjl commented 7 years ago

It's stored in the blockchain database.

OK, I guess I misdiagnosed my experience. Oh well, I did get the correct fork sync'd. Thanks.
